admin.js override different from real code custom_visual_editor_boot_options

[Javinto]

In the readme it says we should set the custom_visual_editor_boot_options in the admin.js file.

However if one uses:

rake refinery:override javascript=admin

it generates:

if (typeof(custom_visual_editor_options) == "undefined") {
  custom_visual_editor_options = {};
}

The latter will not work. It should be the variable from the documentation: custom_visual_editor_boot_options
